IMPROVEMENT IN MACHINES FOR COILI NG, CONDENSING, SHAPING FIBROUS MATERIAL.

Specification forming part of Letters Patent No. 147,769, dated February 24, 1874; application filed February 14, 1874.

To all whom itmay concern:

Be it known that I, JOSEPH HALE, of Somerville, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Coiling, Condensing, and Shaping Fibrous Material; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

The invention relates to a machine for forming fibrous material-more especially j ate and similar raw material -into a coil, and com- )ressin the material and com actin the coils together, and shaping the compacted or condensed coil. I

In the construction of my machine, -I make a cylinder or shell mounted so as to rotate upon a central shaft, and having an interior surface shaped to the form to be imparted to the outer surface of the coil, and the shaft I make as a sleeve, having at one end a headplate clamped to it, against which head the coil is formed and compressed, and at its op-- posite end a gear driven by suitable connec. tion with the motive power that operates the machine. Through this sleeve a screw-shaft passes, said shaft working in a screw-thread formed in a suitable nut, that stands against a stationary bearing in which the rear end of the shaft-sleeve turns, the screw-shaft having a rotative movement in common with the sleeve,

and a feed or longitudinal movement within the sleeve, and the head being attached to the screwshaft by a pin that extends through a slot in the sleeve, the groove permitting the head to slide or move forward or back with the screwshaft, and the head rotating with the sleeve and screw-shaft.

\Vhen the machine is rotated, the screwshaft and head are slid back, so as to leave only space enough between the head and the stationary wall at the rear end of the rotary shell for entrance of the ends of the fibers to be coiled and compressed, the fibers entering through a suitablethroat adjacent to the end plate of the shell. The tubular shaft or sleeve being then rotated until the fibers begin. to wind and hold upon the shaft, the nutis stopped,

and the continued rotation of the shaft will then draw in the material as fast as it is presented, and will wind it upon the sleeve, fillin g the shell and imparting to the coil the shape of the inner walls of the shell, the screwshaft and head being fed forward by the rotation, and the coil gaining in length as the head progresses, the coils being compacted against the head and together, and the compression being increased at any time, if necessary or desirable, by releasing the nut and permitting the screw-shaft to rotate, and the fibers to accumulate upon the sleeve without forward movement. It is in this means for coiling and compacting fibrous material and shaping the compacted coil that my invention consists.

The drawing represents the machine for coiling and compacting fibrous material, and sh aping the compacted coils.

Figure 1 shows a plan of the machine. Fi 2 is a front view of it. Fig. 3 is a sectional elevation. I

I 0. denotes the base; I), auupright or stand, in which and in a bearing, 0, a tubular shaft or sleeve, (1, is journaled. The stand I) is made with an annular bearing or ring, 6, in which is supported the rear part of a hollow cylinder or shell, f, the end of said cylinder abutting against a shoulder, g, and the front of the cyland rotates againstfriction-rollers h. Thetubular shaft extends axially through this cylinder, and has upon its front part a head or plate, 7;, which slides upon the shaft, but rotates with it, a screw-pin, 1, extending through the hub of the plate, and through a slot, m, in the shaft d, and into a screw-shaft, n. The shaft cl may into and driven by a bevel-gear, p, on a shaft, q, such shaft qbeing driven by any suitable geared connection. Into or through the shaft cl extends the serew-shaftn, which shaft can slide freely in the shaft d, but has upon it, outside of the hear ing 0, and resting'against the end of the shaft nut, if held stationary, effecting the forward progression of the screw, (when the shaft (1 is turned in the proper direction,) the shaft (1 and screw a rotating without progression of the screw-shaft, if the nut is permitted to rot me,

tate with the shaft. To hold the nut stationary, a step, t, is used, against which stop the arm 8 strikes, and is held when the shaft is turned, the nut and arm rotatingif this stop is moved from the path of movement of the arm.

The inner surface of the cylinder or shell f is shown as shaped quadran gularl y, (and it may be made of any other suitable form,) and into one side of the cylinder or shell leads a tending from its inner face, are pins 90, against which the fibers catch and hold as they eom Grooves may also'be form ed in the face of the head for a similar purpose. The head has a tongue or tenon that enters the groove m, and enables the head to slide upon the shaft (1 when necessary.

The operation of the machine is as follows: The nut 7', being turned back upon the screwshaft, said shaft is slid forward to enable the head-plate 7a to be fastened to the screw-shaft by the pin 1. Then the head-plate and screwshaft are pressed back until the head-plate or a pin, 00, strikes the shoulder 27, (leaving between it and the face of the scroll a space, into which the fibers can enter through the throat a, and wind upon the sleeve (1,) and the nut 1' is turned back until it strikes the end of the sleeve (1. The ends of the fibrous material to be coiled are then thrust through the throat and the shaft (1 is turned, the nut 1* being allowed to turn with it, and then by the rotation of the shaft and the presentation of the fibers to it, the fibers will catch against the head and wind upon the shaft, being permitted to thus and the face of the scroll. The step t is then brought into position for the arm 3 of the nut, to be arrested by it, and the rotation of the shaft being continued and the presentation of the fibers kept up, the screw-shaft and its head will move slowly forward, the fibers will be coiled and compacted upon the sleeve, and the coil will be shaped to correspond to the inner surface of the shell.

By these means a very close, compact, and hard coil will be made, the density of Which may be increased or regulated by regulating the forward movement of the head k, stopping such movement, and thereby increasing the condensation of the coils behind the head, whenever desirable so to do.

\Vhen the initial end of the coil fills the shell behind'the head-plate, the shell will retate with the hcad-plate, and when the plate passes beyond the shell or cylinder, the rotation of the cylinder will be kept up by the coil, the surface of the cylinder shaping such coil, so long as the shaft (1 is rotated and fibers are presented to it through the throat '21.

I claim- The combination of the hollow cylinder or shell f, the threat a, the rotary tubular shaft (1, the head-plate 7a, the screw-shaft a, and the nut 1", operating to coil and compact fibers or fibrous material, substantially as described.

2. The loosely-rotatingshell or cylinder f, in combination with the rotating shaft (1, headplate It, and screw-shaft 22, substantially as described.

3. The shell or cylinder f, formed with a shaping inner surface, combined with the ring 0 and its throat a, substantially as described.

4.. A stop, If, in combination with the nut r, screw-shaft n, and the head, substantially as described.
